Part 2: Mastering If-Else and Conditional Logic in Python (Part 2)

Continuing from Part 1, let's explore more advanced techniques in Python’s control flow:

1. Using else for Default Behavior

Else catches all cases when previous conditions are False.

temperature = 10
if temperature > 30:
    print("It's hot outside.")
elif temperature > 20:
    print("It's warm outside.")
else:
    print("It's cold outside.")        

2. Nested if Statements

Use nested if statements for more hierarchical decision-making.

 age = 20
has_license = True
if age >= 18:
    if has_license:
        print("You can drive.")
    else:
        print("You cannot drive.")
else:
    print("You are too young to drive.")        

3. Ternary Operators

Shorthand for simple if-else conditions.

age = 15
message = "You are an adult." if age >= 18 else "You are not an adult."
print(message)        

4. Checking Multiple Conditions with in

Use the in keyword to check for values in collections easily.

day = "Saturday"
if day in ["Saturday", "Sunday"]:
    print("It's the weekend!")
else:
    print("It's a weekday.")        

Mastering these techniques will make your Python code cleaner and more efficient.
